TI  - [Study on biodegradation of 2,4-DCP by anaerobic sludge acclimated by mixed 
      mono-chlorphenols].
PG  - 1252-7
AB  - Purpose of this study was to determine the treatability of 2,4-dichlorophenol 
      (2,4-DCP) by anaerobic granular sludge which was acclimated by mixed 
      mono-chlorphenols (2-CP, 4-MCP). The characteristic of degradation of 2,4-DCP by 
      anaerobic sludge acclimated by mixed mono-chlorphenols was investigated through 
      shake flask study and performance of continuous flow anaerobic bioreactors. The 
      difference of degradation of 2,4-DCP by acclimated and unacclimated sludge was 
      also compared. 2,4-DCP was degraded at 50 h and 180 h respectively for acclimated 
      and unacclimated sludge, which testified that acclimated sludge could more 
      effectively degrade 2,4-DCP. Although the intermediate product 4-MCP was present 
      in both reaction system, 4-MCP could be degraded completely after 400 h in the 
      acclimated sludge but accumulated in the unacclimated sludge. Therefore, 
      acclimation by the mixed mono-chlorphenols (2-CP, 4-MCP) could enhance the 
      ability of para- and meta-dechlorination for anaerobic sludge and increase the 
      treatability of 2,4-DCP. The results of continuous anaerobic sludge-suspended 
      carrier bioreactor (ASSCB) indicate that inoculation of the acclimated sludge by 
      mixed mono-chlorphenols can degrade two mono-chlorphenols simultaneously, shorten 
      the setup period, and increase the efficiency of degrading 2,4-DCP. 2-CP was 
      easily degraded with removal rate of over 80% . While the removal rate of 4-MCP 
      was fluctuating within 30% - 80% with changes of its influent concentration.
